GUI transpose code encounter some errors

Hi guys,

I have a code for store and compare photos in a DB and its works fine

clc;

clear all;

close all;

%% Taking an Image

[fname, path]=uigetfile('.jpg');

fname=strcat(path, fname);

im=imread(fname);

im=im2bw(im);

imshow(im);

title('Photo');

answer=inputdlg('Enter the Class(Number from 1-200) ');

str2num(answer{1});

result=ans;

close;

msgbox('Loaded in DB');

%% Feature Extraction

F=FeatureStatistical(im);

try

load db;

F=[F result];

db=[db; F];

save db.mat db

catch

db=[F result]; % 10 200 1

save db.mat db

end

I want to put it in a gui for making an app, but I have this error:

Error: File: load_foto.m Line: 103 Column: 5

"db" previously appeared to be used as a function or command, conflicting with its use here as the name of a variable.

A possible cause of this error is that you forgot to initialize the variable, or you have initialized it implicitly using

load or eval.

The code for thegui loks like this:

% --- Executes on button press in pushbutton1.

function pushbutton1_Callback(hObject, eventdata, handles)

[fname, path]=uigetfile('.jpg');

fname=strcat(path, fname);

im=imread(fname);

im=im2bw(im);

imshow(im);

title('Photo');

prompt={'Insert class'};

introducere='Input';

num_lines=1;

def={''};

answer=inputdlg(prompt,introducere,num_lines,def);

str2num(answer{1});

result=ans;

close;

msgbox('Succesfully loaded');

%% Feature Extraction

F=FeatureStatistical(im);

try

load db;

F=[F result];

db=[db; F];

save db.mat db

catch

db=[F result]; % 10 200 1

save db.mat db

end

for competition I leave also the Feature statistical code:

function [F]=FeatureStatistical(im)

% Summary of this function goes here

im=double(im);

m=mean(mean(im));

s=std(std(im));

F=[m s];

end

load db;

Avoid using that form of load(). Instead, use load as a function assigning to a variable

old = load('db.mat');
db = old.db;

Thanks Walter ! That's it...
